When choosing a base film for thermoforming, it is best to determine whether you need a flexible or rigid film based on your product and the desired packaging properties. Flexible base film is thinner and highly malleable, making it ideal for complex or deep shapes and products where visibility and a good seal are important. Rigid base film is thicker and stiffer, offering strength and making it suitable for products that require protection and a longer shelf life. At Packas, we are happy to help you choose the most suitable base film for your packaging.
